Answer:
second month = 0.5² = 1/4 of original
third month = 0.5³ = 1/8 of original
Explanation:
Answer:
0.5792g
Explanation:
The computation of the mass of the meter stick is shown below:
Let us assume the following items
x1 = 50 cm;
m2 = m3 = 3.62 g;
x2 = x3 = 20.3 cm;
xcm = 22.5 cm
Based on the above assumption, now we need to apply the equation of center mass which is given below:
27.5 m1 = 15.928
So, the m1 = 0.5792g
A). time taken =(2 * V * sin theta)/ g = 3.061 seconds.
b). Range = (v^2 * sin 2 theta)/g = 10.53 meters
Answer:
I₂ = 25 W / m²
Explanation:
Intensity is defined as the relationship between power and area
I = P / A
the power emitted by the sun is constant
P = I A
for the two points of interest
I₁ A₁ = I₂ A₂
energy is distributed on the surface of a sphere
A = 4π R²
I₁ R₁² = I₂ R₂²
I₂ =
let's calculate
I₂ =
I₂ = 25 W / m²
